doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Safe to use 2 3/4" lite loads in 2 1/2" chambers ?

My take on all this is that a 1/4 " longer shell is not the deal breaker. The pressure may or may not rise due to the 1/4" shorter chamber. But from Bell's data I'd allow/account for 15% over if your pressure data is from a 2 3/4" chamber. My data is direct. So I'm confident Im safe for my load. YMMV

Well as I am now in the states for a while with my old 1885 P Webley with a Jones underlever (so a strong lockup there) I will have to check some soft loads out, maybe cheap dove from mart-wal will do the trick.
It has to be less dangerous than working in Juarez.

A Stephen Grant sidelever and you have a guy who sells 2 1/2 " shells nearby !! Why ??, best, Mike

Those cheap dove loads are loaded with enough pressure to cycle an improperly maintained 400 dollar autoloader. They have to be, or they wouldn't sell at WalMart. They are almost certainly well above 10,000 psi, far above what I would feed a damascus Grant or Boswell.

I have a close friend who owns what was once a beautiful cased damascus Charles Boswell with the right chamber blown out from using loads with too high pressure. Yes, I warned him beforehand, but he didn't heed my warnings.

Agree with Stan. "Light" by WalMart standards does not mean low pressure.

Agreed. I read this thread and I keep asking why????

As recommended, I've just placed an order with RST for 6 flats of 2 1/2" 12 ga.

Thanks again to all !

Thank the Lord teeny, that side lever will go on for another 80 years best

Hi 2 Piper,
By "Roll crimp 2 3/4" I meant as a reloading thing,not factory. Like taking a fired 2 3/4" pie crimped shells,cutting the open shell to 2 1/2", load it n roll crimp it.I've never trimmed or even roll crimped a shell before, just curious if this would work crimp wise..with the roll being applied to a formerly pie crimped shell.
Its prolly still dumb, I just wanted to at least be dumb with the right facts, ha ha
cheers

Franc;
I am following what you mean now. I have not actually tried that so not positive if you could get a good roll crimp with whats left of the folds or not. Another option that was discussed a good bit some time back but haven't seen t mentioned lately is the "Hardin" crimp. For this you cut the 2 3/4" hull down to proper length then load as normal a load of proper intensity from a 2 3/4" menu. Then place a top wad on & run through the regular fold crimp stations. Supposedly this will make a secure crimp with a big hole in the center. quicker & easier than applying the roll with no extra tooling required except for cuttin the hulls.
